Metallic coatings－Determination of the mass for hot dip galvanized coatings on ferrous materials－Gravimetric method

This standard specifies the method for determining the mass per unit area (surface density) of the hot-dip galvanized layer on ferrous metal materials. This standard is applicable to samples whose surface area is easy to determine (such as materials in the shape of plates, wires, tubes, etc.). If the sample is too heavy to be implemented according to the requirements of Chapter 5 of this standard, other methods are used to determine the mass of the hot-dip galvanized layer.
